16 December 2018 11:28 We make an exact copy of the pressed-steel magneto A/R and air levers as used on all long-stroke Manx Nortons. It clamps onto the handlebar. High quality chrome finish. K McI

16 December 2018 10:06 I am checking the parts listed for the garden gate models, I have a 1947 500 and am looking a few parts that I can see listed but can you clarify the air lever - is this a pressed steel lever with chrome finish? what about advance/retard?

10 January 2017 02:06 I have a 1960 Manx Norton M30 I ride on the road. It has a Newby belt drive and clutch, coil valve springs, and a Kabota tractor alternator hidden in the primary. Castor based oil is illegal here, and I am down to my last pint. Alternatives?

Is this a manx? - (read 182416 times) Reply
25 September 2011 06:10 I am starting to restore a old Norton I have had for 37years, and have a question about the frame number. This is what I have vertical line of numbers 53319 I am assuming serial number, then horizontal line starts J1 and it is getting hard to read the rest of the model number, Is there any way to tell from just the serial number??? The right upper frame tube has a indent that looks like it is for the bevel drive of a long stoke motor. is the Manx the only bike to have this indent? the upper rear transmission mount is not welded to the frame( normal for a 54). Being a J make it a 1954 and the serial number agree with that, It seems it could be a J11M2 M40 Manx or a J122 dominator 88 (why would a dominator need the indent?). I just do not want to start and find out later that it was a Manx, I might take a different direction rather than build it back as a Triton/Weslake

Cams and cam follower wear - (read 97430 times) Reply
29 May 2011 10:33 Hi Just a reply on the oil used, tried every thing from Shell semi synthic to Belray. Oil type is not the problem rather I believe oil quantiy to the cam box. Ken my engine is fitted with the adjustable oil supply to the cam gear and you said to me many years ago that I should chuck it and fit a standard relief valve. I think I will do this as I am thinking of firing the old girl up again. I also may fit a new oil pump as the original looks a bit tied. I will make a run over to NZ in near future to discusss in person. Best Regards Mark

Dating a works engine? - (read 103469 times) Reply
23 December 2010 09:46 Thanks to Geoge Cohen, my engine has been dated as a 1937 model which was destined for the Isle of man. 350cc machines from 29 to 39 used a separate lot of numbering. From 29 to 36 they used 1000 to 6200. From 37 to 39 they used 6201 to 10700. Yes, 5 numbers were used from 1939. The letter code was used from 1946 onward. Hope this helps others.....regards Noel
